A person has atherosclerosis. Which pathophysiologic process has occurred?
Fatty streaks produce foam cells that accumulate and block the flow of blood in the vessel.
Macrophages release enzymes and toxic oxygen radicals that create oxidative stress.
Vasospasm in the small arteries from an imbalance between vasodilation and vasoconstriction produce fibrous plaque.
Significant T-cell activation and a lack of endothelial precursor cells affect blood vessel linings.
Macrophages release enzymes and toxic oxygen radicals that create oxidative stress.
A person with an MI is releasing angiotensin II. How should the nurse interpret this finding?
Releasing angiotensin II is
beneficial; it helps the heart pump effectively.
counterproductive; it causes the heart to work harder.
beneficial; it decreases the release of catecholamines.
counterproductive; it causes myocardial stunning
counterproductive; it causes the heart to work harder.
